The flag at Kingston police station is being flown at half-mast in tribute to murdered officer Keith Palmer, who was killed during a terror attack at Westminster.

Politicians and residents have united in paying tribute to Mr Palmer, identified by the Metropolitan Police last night as one of three innocent people killed when a terrorist attacked Parliament yesterday.

The 48-year-old officer died after he confronted the terrorist who rammed his car into pedestrians on Westminster Bridge at about 2.45pm.

Officers in Kingston met at the police station this morning to discuss their response to the attack, with the flag now being flown at half-mast.

Kingston MP James Berry was in Parliament when the attack began, describing on social media how ministers were kept in “lockdown” inside the chamber.

Police officers were also stationed at his constituency office in Ewell Road, in Surbiton.

Mr Berry tweeted: “We're on lockdown in Parliament - my thoughts are with the police officer & members of the public injured in these barbaric attacks.

“My thoughts & prayers are with those killed & injured on Westminster Bridge in today's dreadful act of terror, as well as their loved ones.”

Paramedics attending to the victims outside Parliament

Armed officers shot the attacker inside the Houses of Parliament security cordon shortly after the attack. He was shot dead by police, the Met confirmed yesterday.

It was revealed in Parliament today that the attacker, who has yet to be identified, was known to MI5 and was British born. About 40 people were injured in the attack.

Kingston Council leader Kevin Davis tweeted: “Terrible events at Westminster. I left an event at 3pm in area and no doubt that London safer for efforts of well organised police service.”

Prime Minister Theresa May called the attack “sick and depraved” during an address outside Downing Street last night.

The first victim at Westminster Bridge has been named as Aysha Frade, 43, a Spanish teacher on her way to pick up her children from school.

Esher and Walton MP Dominic Raab called yesterday's attack “gutless”, adding that he was “very grateful” for the safety of his team at the commons.

Mr Raab said: “We are still waiting for all the facts to emerge. For my part, I think the most important thing right now is to honour those who lost their lives, care for the injured, and pursue anyone who had a hand in the attack to bring them to justice.

“Perhaps the most important thing, is that we – as politicians, and as a country – do not blink or flinch before such cowardice.

“So, I have just finished attending to my daily constituency casework, and I will now be heading over the the chamber for the Prime Minister’s statement.”

Surrey Police also released a statement yesterday following an attacks saying they are “already operating at a heightened state of security against a severe threat level which has been in place since 2014.”

A spokesman said: “The Force continues to liaise with national and regional colleagues as the investigation unfolds.”

Chancellor and Weybridge MP Philip Hammond tweeted his “shock” after the attack.

His assistant Hannah Edwards said that he and his staff were “shaken”, and were locked down in his Parliamentary office with his protection officers.
